Drowned Woman Seeks Revenge on Group of Men

by Candy
(Australia)

Hi,I saw a movie maybe in the '70s or early '80s about a group of men who push a woman in a car into a lake or river believing she's dead but she is unconscious and drowns.

She later comes back to take revenge on the now older men's sons, killing them one by one until one of the men drags the car out of the water and gives her a proper burial.

Do you know which movie it is?

Thank you,
C
